There is a main switch to turn it on and off which, on some makes of toaster, is operated when the bread-carrier tray is moved into the "toasting" position. On some other makes of toaster the main switch is operated when the toast color control is operated, usually by turning a knob or sliding a slider.
Depending on the make of toaster this "browning level" control either sets a particular "toasting time" or a particular "color". In either case, when the toast is done - meaning when the temperature has reached the manually-set point - a thermal switch shuts off the current to help prevent the toast from burning.
For safety reasons, to help prevent starting house fires, on modern toasters there is also a second, high-temperature, thermal switch. This is designed to shut off the current if the temperature gets so hot that the toaster could burn not only the toast but also nearby surfaces such as the worktop or table it is standing on, a wooden cupboard, curtain, etc. Can't have toaster heating up the room!

What is the simple device that opens and closes an electrical unit called?
A device that opens and closes a circuit is called a switch.
What determines whether a pressure switch opens or closes on a rise of pressure?
A pressure switch opens or closes in response to a predefined pressure setpoint, which is determined by the internal mechanism of the switch. When the pressure in the system rises and exceeds this setpoint, the switch activates, either opening or closing an electrical circuit. The specific action—whether it opens or closes—depends on the design of the switch, which can be configured as normally open (NO) or normally closed (NC). Additionally, the pressure hysteresis settings can influence the exact point at which the switch resets after activation.
Which switch opens the circuit on a tv?
The power on switch
What is the part of a circuit the closes or opens the circuit?
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
What opens or closes an electrical circuit?
That function was traditionally implemented in the form of a mechanical deviceknown as a "switch".The practice became so firmly embedded in the art and science of electricitythat the word became the generic term for any device that could performany similar function, so that now we have "switching transistors", integrated"CMOS switches", and even central office telephone-circuit "switches".
